The two first plants to have moved onto land and adapted to better suit their needs, have a lot of similarities between the two and a lot of differences! For example, in both Bryophytes and Pteridophytes they both have an archegonium and antheridium, aswell as spores which are wind-borne and require the environment to be humid and windy before release. Both of these plants are seedless and use the process of mitosis and meiosis. The sperm of both these plants are flagellant meaning they can swim to the archegonium when fertilization is to occur. The sores that are released will both create a gametophyte in the early part of reproduction.
Differences between the two plant species consist of physical and physiological differences! Pteridophytes are vascular plants that contain vascular tissue and features. They contain a xylum which transport water from the roots to the shoots and phloems which transport photosynthesis products from the shoots to the roots. In contrast, Bryophytes do not contain any of those features as they are non- vascular which makes them smaller sized plants and located lower to the ground! Bryophytes rely on living in moist areas with lots of water because they are not vascular plants that can transport water throughout the whole plant unlike Pteridophytes! Within the gametophyte stage in Bryophytes the archegonium and the antheridium are located in two different locations whereas during the gametophyte stage in Pteridophytes, the archegonium and the antheridium are both located in the gametophyte, just at separate poles! As for the features of these two species of plants, the Bryophytes are dominant in the gametophyte stage whereas the Pteridophytes are dominant in the sporophyte stage. The Bryophytes contain capsules that release reproductive spores whereas the Pteridophytes have a sporangium that release the reproductive spores!
